What JÄSPI does

JÄSPI is the consumer-facing brand of Kaukora Oy, a privately held Finnish manufacturer of heating and domestic hot water equipment founded in 1976 (with the related Jämä brand tracing back to 1949) and headquartered in Raisio, Finland. The company designs and produces ground source heat pumps, air-to-water heat pumps, electric and oil/biomass boilers, domestic hot water tanks, buffer tanks, and grid-balancing electric boilers at two Finnish plants in Raisio and Turku. Its product portfolio spans the full spectrum of northern-European heating sources, and selected models such as the Jäspi VLM 300 are reported to be installed in roughly every second Finnish detached house, with the Jämä Star RST Inverter claiming a market-leading SCOP of 5.4. Connected products are managed through the myUplink remote monitoring platform, which was renewed in 2024.

The business operates on a hardware-sales model with revenue generated from the sale of heating equipment to end customers. JÄSPI distributes exclusively through a nationwide network of authorized dealers and installers in Finland, who quote, sell, install, and service the equipment on a project basis; the company also runs a dedicated project sales team for large properties, housing cooperatives, industrial sites, and district heating plants, plus dedicated export sales representatives covering Sweden, Norway, Russia, Germany, and the United Kingdom (exports were approximately one-third of 2016 turnover). Pricing is not publicly disclosed and is set per project, with customer financing offered through Jäspi Heating Financing (EUR 2,500-50,000). A five-year factory warranty (introduced 2023), the Avainlippu domestic-production certification, and participation in events such as Energiamessut underpin the trade-channel and brand positioning. The company produces over 50,000 heating devices per year, has manufactured nearly 2 million units since inception, and operates with a headcount in the 11-50 range.
